The UN Security Council comprises five permanent and ten non-permanent members. The UN Charter and standard texts state that the ten non-permanent members are elected by the General Assembly for a term of two years; retiring non-permanent members are not eligible for immediate re-election [2].

Therefore the correct choice is a two-year term for non-permanent members of the Security Council.
